A furnace that runs poorly, short-cycles or fails to produce heat is a comfort-service concern. A gas odor, propane alarm or suspected carbon-monoxide (CO) exposure is different.
If you smell gas or a propane alarm sounds, evacuate and get emergency or gas-supplier help from a safe place. Do not operate electrical switches, the engine or generator. For fire or suspected CO exposure, leave the RV for fresh air and call 911; do not re-enter until responders allow it.
